Night lighting highlights how to avoid the three major unscientific points of urban culture?

Since the end of the 1980s, Shanghai has taken the lead in the renovation and construction of the nightscape lighting project on the Bund and Nanjing East Road. Afterwards, the nightscape lighting construction in Beijing, Tianjin, Guangzhou, Dalian, Qingdao, Chongqing, and Shijiazhuang has rapidly developed. . Nightscape lighting has become a symbol and symbol of urban development and has become an important measure of the degree of urban culture.

The advantages and disadvantages of lighting design reflect in part the overall level of urban development, but there have also been many problems in the development. Here, Zhimei Lighting sets forth the following three major unscientific points in proposing night scene lighting: excessive light brings light pollution, light damage to buildings, and abuse of high energy-consuming glare lamps.

Light pollution due to lighting brightness requirements:

The long-term commitment to green low-carbon lighting design says that artificial light sources are created to improve life functions and achieve an efficient, bright city and a bright family life. However, with the rapid development of lighting technology and design techniques, especially after the development and use of LED lamps, the orientation to improve the quality of life has changed. Today's lighting has entered the era of high brightness.

If the sense of lightness, modernity, and science and technology are the effects of lighting, then a large number of doubts arising from "brightness" are blamed on the energy waste of "social evil", which is also an unavoidable fact.

In this regard, cited the classic case of flexible use - lighting design of Ginza, Chanel, Tokyo:

Ginza is one of Japan's most prosperous business districts, and its bright project is remarkable. In the depths of the neon there is a building where everyone is bright and I am dark, that is, the flagship store of Chanel Tokyo. Its lighting design abandons the bright colors of the LED, using only black and white colors. At night, the LED will create a classic Chanel totem. In the eyes of tourists, Ginza is very bright, but this building is very dark; other buildings are dynamic and flashy. This building is classic and warm. Once people have mastered and can freely use LED light sources, lighting applications such as buildings, business districts, landscapes, and bridges all use a large number of luminaires to increase light illumination and use dynamic and colored lighting to render light atmospheres. It has become a place where colored light is put to rest. People's living environment has become a test field of light, it is indeed a "dangerous" thing!

Take into account the historical and cultural features of the original art and landscape of the building itself:

In the current lighting project, designers and constructors taking into account the lighting effects, while taking into account the shape and connotation of the building itself is a difficult point. Night lighting is culture, it is art. Taking care of the original historical and cultural features of the landscape and architectural art features is a very important design concept for night scene lighting, and it is also one of the important contents of landscape environmental protection. Nightscape lighting fixtures should be concealed, especially large-scale public buildings, ancient buildings, antique buildings and European architecture, beautify the night view of tile roofs or vaults, and prevent the destruction of classical architectural architectural beauty. The lighting must be beautified during the day, and at night it should be "seeing no light." However, at present, there are quite a few well-known buildings in China that have been damaged by naked lights and lamps.

Including billboards and light boxes in commercial streets, residential buildings, public squares, etc., in the absence of regulatory restrictions, the light boxes are installed arbitrarily, the light strips are staggered, and even the light boxes are stacked in light boxes. The appearance of many buildings is blocked to varying degrees. , And hinder the appearance of the building, but also affected the internal sight of the building. Seriously conducting scientific research on lighting fixtures or non-standard lighting fixtures, adopting LED or other new lighting technology is the way to research and solve the historical and artistic features of the original landscape.

Designers must master the use of appliances with caution and use of energy-intensive glare lamps:

Speaking of the design concept that has persisted for many years, Zhimi Lighting related designers said that “With the widespread dissemination of low-carbon environmental protection concepts, the use of long-life, high-efficiency, energy-efficient light sources is our design philosophy.”

At present, most of the city's nightscape lighting uses LED, metal halide lamps, high-pressure sodium lamps, and high-pressure sodium lamps. The outstanding characteristics of these light sources and incandescent lamps are high luminous efficacy, long service life, and lack of accessories. Sex investment is larger. The relevant specifications for lighting illuminance in China are that the protection rating of the lamp housing installed outdoors should not be lower than IP54; the protection rating of the buried lamp housing should not be lower than IP67. While selecting the lamps and lanterns strictly in accordance with the relevant parameters, the glare limit and the Under light conditions, high efficiency lamps should be used. The efficiency of floodlights should not be less than 65%.

Of course, under the premise of energy saving, the final overall plan for lighting effects should be firmly in the hands of designers. The LED light sources that have become popular in China in recent years are the first choice for most of the lighting industry. There is no doubt about LED products. However, LED lighting is a priority for LED lighting projects. This has already become the beginning of many designers' career bottlenecks. There are many designers who like to be jailed, thinking that LEDs are for "shining," "brilliance," and "technology." In fact, only designers master the use of appliances, lighting design can achieve considerable development.

Lighting is to beautify the architecture, beautify the space, and beautify the environment, and ultimately it will beautify people's hearts. The rational use of light seems to be a simple trade-off question. It is essentially a process in which a designer learns from life, sublimates his skills, and consolidates his inner heart. In the lighting design, the light source shape and brightness design, the light source and the building complement each other, the optimal use of lamps and lanterns, the three major points are closely combined in order to produce good results.
